Letters-Patent No.v 94,074, dated fugust 24, 1869.;V

The-Schedule referred to in these Letters Patent and making part of the same.

vTo all whom 'it may concern y Be it known that 1', J osIAH BUzBY, of Crosswicks, in the county of Mercer, and State of New Jersey, have invented a new and improved'WatelJvVheel; and I do hereby declare that the'following is a full, clear, and vexact description thereof, which will enable others skilled in the art to. make and use the same, reference being had to the accompanying drawing, forming part .0f this specification, in which- Figure l represents a .plan or top View, partly in section, of my improved water-wheel.

Figure 2 is a detail horizontalsection, on anenlarged scale, of a chute-plate andlgate.

Figure 3 is a detail sideelevation of the same.

Similar letters of reference indicate corresponding parts. l The object of this invmtion is to construct a waterwheel sothatimnurities v:passing through it, will not be able to injure any of its parts,fancr which wiil auto'- matically regulate its chute-openings, so that the. same will, for a suitable pressure, be always proportionate to the outlet, and to the frictionof the shaft; also, to

' so construct the gates that-the orevices between them andthe wheel-case will be water-tight, so that no un necessary loss of power, by waterpassing through such crevices, is incurred.

The invention consists, rst, in pivotingthe chuteplates to the wheel-case, so that they can be forced outward bympurities carried by the wheel, and, in case the pressure'within the case should exceed that from-v the outside, thechute-openings will thereby be auto matically regulated. l

The invention consists, secondly, in providing packing-stripsbn the gates, andfonthe opposite edges of the chute-plates, so'that'water can only pass toward the wheel through the chute-openings, and not through any other crevices or apertures.

The invention iinally consists in'making the gates of segmental form,or rather, in making their outer faces curves of circles', described from their respective pivots, so that they 'will always be'the requisite distance from the opposite edge, to. work without any material friction, and always reliable.

A, in the drawing, represents a waterwheel of s uitable construction.

B is its shaft.

C, the case.

D, the plate.

Between theoutward ange a, of the case, and the cover D, are arranged the chute-plates E E.

These are of triangular, or nearly such shape, tapering toward their discharge-ends, and are, by means of pins b b, that project from their upper'and lower edges, pivoted to the cover D and ian'ge u, as shown.

Each chuteplate can 'thus swing on its pivots, b.'

the flange a and cover D, or either, small pins, c'c,

, against which the innersides of the chute-plates strike,

to be held in their lmost inward position.

The inner faces of the chutefplates are notched, as iniig. 2, so that the pins c will be concealed. in such notches, so that theywill not be in the way of the `water.

It is evident, that when the pressing of the water within the case exceeds 'that on the outside, the chuteplates will be swung out to regulate the chuteopenings, and to thereby automatically adjust themselves to the power applied. In case any impurities or solid matters are carried into thexwheel, and held on the outer parts of the wheel buckets, the chute-plates will yield to them, and no parts of the wheel or. chute will be injured, the chute-plates falling hack to their original position as soonassuch matter haspass'ed.V

-F -F- are the-gates.

They are plates with vcurved outwardfaces, andare, by means of arms d d, connected with the Vertical shafts or pivots e e, that aresnpported in ears, f, of the chuteplates.

The curve of thev outer face of each gate is described from the axis' of the pins e, of each gate, as centre.

The face ofLjeach `gate plays against the back edge of the next chute-plate, said back edge containing a leather or other packing-strip, g, as shown.

The face of the gate working against this packing-- strip, will not produce much friction when made, and

will still close tight.

The packing-stn'pg is fastened to the chute-plate by a 1ib,'h, which is fastened, by Ameans of a screw or screws, i, as shown, s0v that the strip, when worn, can be readily removedv and replaced.

The upper and lower edges of the gates contain, also, packing-strips j,

plates or bars k wedges, l, or their equivalents.

From the outer part of 'each gate projects a pin, in, 'which is, by means of a rod, n, connected with a wristpin, o, that 'projects from a pinion, p, hung ou the top.

plate D of the wheel-case.

These various pinions mesh into a gear-wheel, G,-

that is fitted loose around the shaft B. By turning this gear-wheel by suitable mechanism, the gates will all be properly adjusted.

rl`he device foroperating the gates may, however, be ofdii'erent construction, to operate to equal advantage.

Having thus described my invention,

That .L elaim as' ne y and desire to secure by Let- Y ters Patent; is-

made'of leather or othersuitable material, land fastened in grooves of the gates, by k, that are fastened by means of 1. The turbine water-wheel, having arranged around the periphery thereof', a series o f pivoted vibrating chutesv E and stops c, whereby the said chutes are rendered adjustable and yielding to the passage of any unusual substance, without breakage or injury to any of the parts, and yet without possibility of coming in contact with the buckets, all as described.

2. The said chutes, with their discharge-ends drawn to a sharp edge, andarranged in close proximity to the buckets, while the'iplane of the chute-face is at right angles, or nearly so, to that of the bucket-face, thus causing the current of water to mpinge with all its natural force, substantially as setforth.

3, The combination, with the described chutes E, of the swinging gates F F, with packing-strips, arranged as described, so'as to regulate the ingress of water, or to shut it oli' entirely, in the manner specified;
